No smoke or water wakes on landings? help

Hi all, I have added some effects to the effect file but it seems I can no longer get a wake or splash effect on water landings. In addition, I am not getting smoke effect when the wheels touchdown on a runway landing. I checked and I believe all of the original files are in the effects file (C:\Program Files\Microsoft Games\Microsoft Flight Simulator X\Effects) There is an empty texture file at the top of the effects, I don't know if that's an issuer. Is there a setting in the fsx.cfg file I should check. Thanks for any and all help
